1. PLC COMMUNICATION DATA TRANSFER The data transmitted between the PLC and the Z-TIO-C/D module is compiled in the PLC communication data map. In the PLC communi cation data map the communication data is classied into system data, monitor groups, and setting groups.

System data Request item number, Request commands, Setting group communication state, etc.

Monitor group Measured value (PV), Comprehensive event state, etc.

Setting group PID/AT transfer, Set value (SV), etc.

PLC

PLC register

Z-TIO-C/D module 1

Z-TIO-C/D module 2

For the communication data, see 2. PLC COMMUNICATION DATA MAP .

1.1 Data Transfer Type Data transfer between PLC and Z-TIO-C/D m odule are executed by the request item number and the request command.

Request item number This command sets the communication data of th e setting group that is transferred. Set transfer of all communication data of t he setting group, or transfer by one data item. Data transfer are executed by request command.

Setting range: 0 or 1 to 64 (Item number) • When set to 0, all communication dat a of the setting group is transferred. • When set to a number from 1 to 64 (item number), only the set communication

data item is transferred (t ransfer by one data item).

For the item number 1 to 64, see “ Table 2: Setting item selection (Communication data of setting group) ” of Z-TIO PLC Communication Quick Instruction Manual [PART1: Preparation] (IMS01T11-E ).

Note that communication data that is not selected (set to binary: 0) in setting item selection of the PLC communication environment is not transferred.

Request command

For the request command, both “setting request bi t” and “monitor request bit” are available.

• Setting request bit (PLC → Z-TIO-C/D module) This command requests that the Z-TIO- C/D module read the communication data of the setting group on the PLC side. [Processing] (1) Just when “1 (decimal numbers: 1)” is se t to the setting request bit, the Z-TIO-C/D

module starts reading the data from the PLC side. (2) The setting group communication data set in “Request item number” is transferred

from the PCL to the Z-TIO-C/D module. (3) After data transmission is complet ed, the setting request bit becomes “0.”

• Monitor request bit (PLC ← Z-TIO-C/D module)

This command requests that the Z-TIO-C/D module write the communication data of the setting group on the PLC side.

[Processing] (1) Just when “1 (decimal numbers: 2)” is set to the monitor request bit, the Z-TIO-C/D

starts writing the dat a to the PLC side. (2) The setting group communication data set in “request item number” is transferred

from the Z-TIO-C/D module to the PLC. (3) After data transmission is completed, the monitor request bit becomes “0.”

When setting both the setting request bit and the monitor request bit to “1,” set the bits simultaneously. If se t separately, the bit set later may be disregarded.

Monitor group The monitor group communication data is always transferred as monitor item data between the PLC and the Z-TIO-C/D module rega rdless of the request command setting.

1.2 Data Transfer Procedures Change each set value of Z-TIO-C/D m odule from the PLC after the initial settings are made. If each set value of Z-TIO-C/D module is changed from the PLC without setting the initial values, it is re-written to “0” with each set value of the PLC at that time set to “0.”

Initial setting

Data setting When the setting group communication data is transferred from PLC to the Z-TIO-C/D module.

Data processing precautions The data type is treated as binary data with a sign and without a decimal point. For this reason, carefully express and set the data. (Excluding the bit data)

2. PLC COMMUNICATION DATA MAP The data that can be communicated by the PL C and Z-TIO-C/D module is compiled in the PLC communication data map. The data map indi cated in this manual is the data map of factory set value. The data map ca n be changed using the PLC communication environment items below.

• Register type • Setting item register bias • Register start number (High-order 4-bit) • Monitor item selection • Register start number(Low-order 16-bit) • Setting item selection • Monitor item register bias • Slave register bias

For the PLC communication environment item, see Z-TIO PLC Communication Quick Instruction Manual [PAR T1: Preparation] (IMS01T11-E ).

For communication data not described in this manual, see the SRZ Instruction Manual [PLC Communication] (IMS01T13-E ).

Turn on the power of the Z-TIO-C/D module, and the PLC.When the PLC communication start time (factory setting: 5 seconds) elapses, writing of the system data begins.

When the monitor request bit (bit 1) of request commandof the PLC register is set to “1 (Decimal: 2),” th eZ-TIO-C/D module begins writing the setting group to th ePLC.

During data write: Treat the data of all items as inconsistent during the data write.

If the monitor request bit (bit 1) of the request commandof the PLC register is “0,” this indicates that writing of dat ato the PLC is nished.

After the system data is written, the Z-TIO-C/D modul ebegins writing the communication data of the monito rgroup to the PLC. When monitor group writing starts,“system communication state” changes to “1.” When the system communication condition becomes “1, ”PLC communication can be performed.

Because all communication data of the setting group i swritten to the PLC, the request item number of the PL Cregister is set to “0.”

When writing is nished, the Z-TIO-C/D module writes th ecommunication state of the setting group to the monito rcompleted bit (bit 2) of the setting group communicationstate of the PLC.
